Peatlands are a type of wetland ecosystem characterized by the accumulation of partially decayed organic matter, known as peat. This process occurs in waterlogged conditions where oxygen is scarce, slowing down decomposition. Peatlands cover approximately 3% of the Earth's land surface and are found in various climates, from tropical to arctic regions. They are particularly widespread in northern latitudes, such as Canada, Russia, and northern Europe.

The formation of peatlands is a slow process, with peat accumulating at rates ranging from a few millimeters to a few centimeters per year. The type of vegetation present significantly influences the peatland's characteristics. Sphagnum mosses are a dominant plant group in many peatlands, contributing to their acidic and waterlogged nature. Other common plant species include sedges, cotton grass, and various ericaceous shrubs.

Peatlands play a crucial role in global ecosystems. They are significant carbon sinks, storing vast amounts of carbon – estimated to be twice the amount held in all the world's forests. This carbon storage helps regulate the Earth's climate. Peatlands also act as natural filters, purifying water and regulating water flow, which can help mitigate floods and droughts.

Despite their ecological importance, peatlands are threatened by human activities, including drainage for agriculture and forestry, peat extraction for fuel and horticulture, and wildfires. The degradation of peatlands releases stored carbon into the atmosphere, contributing to climate change. Conservation and restoration efforts are therefore vital for preserving these unique and valuable ecosystems.
